Offender: Bumper sticker portfolioWhy: Look, I made the honor roll. You made the honor roll. At this point, they should just call it "the roll." Also, keep your dog posts where they belong: Your Facebook feed.

Offender: Trucks with obnoxious drop kitsWhy: While it's not actively bothering anyone like a jacked-up truck, look at this thing. It's a crime against common decency is what this thing is.

Offender: Trucks with grille guardsWhy: No off-road truck is complete without a front-end brush guard. Then again, I don't see your truck off any established roads.

Offender: HummersWhy: Apart from being a moving symbol of America's previous economic crisis, these garish vehicles are the automotive equivalent of wearing camouflage as a fashion statement.

Offender: Mismatched mufflersWhy: Apart from their garish appearance, these aftermarket exhaust pipes often emit horrendous sounds when a car accelerates.

Dubbed "rolling coal," truck drivers are willfully modifying their vehicle's exhaust to stick it to the man: In this case, U.S. President Barack Obama, the EPA and any other namby-pamby environmentalist who wants cleaner air.

It can cost around $500 to install the smoke stacks, putting this right up there with throwing your money out the window.
